Hi
Is your current version set to Elementor 3.5.6?
Please note that it is necessary to update Elementor plugin to the latest version. WordPress plugin updates cannot be ignored as there are several security updates that are released by WordPress core and by all the plugins. Ignoring an update for both WordPress or any plugin in the marketplace leaves your site vulnerable.
If your site is on managed hosting then the hosting provder may automatically update WordPress along with the plugins of the site. Please ask your web host to block any auto updates.
Can you please share a screenshot of the Elementor plugin in the Plugin page like I have shown here – https://snipboard.io/y5JNoL.jpg
It should say “Enable auto-updates”, is this showing the same for you for the Elementor plugin?
Again I would insist that you update Elementor plugin and contact the third-party theme’s support team regarding the incompatibility issue that is showing up on your site. This is the best, secure, and recommended approach to solving the issue.
